The water being flaky was my fault. I hadn't included his water tweak along with the land tweak. Edit: At 1280x1024 with 4xAA and Bloom enabled, I was in the mid 20s still (outside shots, inside the framerate is much better). This is using the land and water tweak. The framerate would be much better without those tweaks. Also, some new drivers are supposed to be available for Oblivion tomorrow so maybe that'll help also. In my screenshots, I'm using HDR while AA is off.
